See if Auto Zone or some other parts house or friend to check an see if any codes show up if they do write them down or do like some do and buy Alfa OBD: https://alfaobd.com/ along with a OBD reader so you can read them your self..

I did AutoZone and Napa before the dealer and there $50k computer and all have shown. NO CODES but they light stays on

Is the CEL on with the vehicle running or just key on? The only time I came across a CEL with engine running but no codes it was a faulty PCM sending a request to turn on the CEL.

Did they reset the light to "clear" the no code and did it come back on?

I was thinking the same thing as this guy. Any mid level or higher scan tool should be able to tell you if the CEL is being commanded on and for how many miles/ warmup cycles its been on. that should point you to weather or not it may by a PCM issue.
